| Abstract: |
| Objective To investigate a monitoring method of particle size of dust sands in the air. Methods The collection effect and sample difference by the two different collection methods, i.e., the windward intercepting collection way and the static balance collection way, were compared to discuss the accuracy and suitability of the wet laser particle size analysis and the SEM particle size analysis. Results The static balance collection way got a lager sample amount than that by windward intercepting collection way, and also the particles sizes were obviously different by this two collection ways. On the aspect of particles size analysis, the wet laser particle size analysis was more suitable than SEM. Conclusion The static balance collection way can be used in combination with windward intercepting collection way to process sand collection, and the wet laser particle size analysis can be used to grasp the particle size distribution. |
